To all whom it may c n n: hinged to an end bar of the frame.-2, as indi-,

The several 60 5 borough of Manhattan, in the county and uprights have pivotal connection with the State of New York, have invented a new and table 5, and they are held in upright position Improved Fabric-Foldin Machine, of which whenthemachme is-in operation by means the following 1s a full, ear, andexaot do of tie-rods 10,, here shown as pivotallyconscr1 tion. h 4 nected to the uprights. 6iand having hook 65 IO invention relates to improvements in portions 11 for en aging in kee ers 12, atmachines for foldin or forming layers of fab-- tached to the uprig, ts 7.

Fig. 10 s ows a clothspreading the fabric u on the cutting-table cutter, and Fig. 11 shows a modification in as the machine moves back and'forth. This 'roo means comprises apair of rock-shafts 2 25, Referrin to the drawings, 1 designates a having bearings in boxes on the side-memcutting-tab e, movable along the top of which bers of the frame 2 and carried by these bars is anarriage comprising a frame 2, su ported 24 25 are fabr1c-carrymg bars 26 2"7', the adby wheels 3, whlch enga e with trac s 4- on jacent'edges of the opposite bars beln some- 105 the table-top. These w eels 3 will preferwhat sharpenedin other words, t c said ably be provided with rubber tires. Mountbars are wedge-shaped in cross-section. The ed on' the frame 2 is a sup lemental table 5, bars are connected to stem portions 2 8, which on which the oods to be placed in layers are move through-openings in the rock-bars 24 arranged. T e table 5 is supported at one 25, and the central stem of each bar has 'a 1 1 10 "5 5 end by up hts 6 and-at the other end by upthreaded portion 29,- movable through a rights-7. he uprights are pivoted or sleeve 30 on its rocking bard These threaded portions en age with ratchet-wheels 31, designed at the end of movement of the carriage to be engaged-by fingers or pawls 32 for imparting'rotary movement to the ratchetwheels, thus drawing upward the carrierbars to accommodate them to the growing thicknesses of material spread u on the cutting-table. The carrier-bars 0 each rocking bar are moved simultaneously, because the upper ends of the stems are connected by a cross-bar 33. Connected to one end of the rocking bar 24 is a downwardly-extended arm-34, having a rounded end, and a similar arm 35 extends downward from one end of the rocking bar 25, and mounted on each carrierbar is-an inclined cam-plate 36, the outer end of which is supported by a pin 37. The object of this construction will hereinafter appear.

Arranged at or near the ends of the cuttingtable are fabric-clamping devices, here shown as consisting of plates 38 39, these plates being mounted to swing vertically on cross-bars 40, attached to clamping-bars 41, the ends of said bars 41 being turned downward and inwardto enga e over the edge of the cuttingtable, as clear y indicated in the drawings,

and they are held as adjusted by clampmgnuts 42, and outward of each bar 41 is an upwardly-extended arm 43, provided with a buffer 44, of rubber or other suitable material, against which the carriage may strike upon reaching the ends of the cutting-table. Arranged at one side of each clamping-plate 38 or 39 is a board 45, having an incline 46 at its upper end designed to be engaged by the depending arms 34 35, and on the under side of each clamping plate are toothed jawplates 47, designed to engage'with the fabric to hold the same on the cuttingtable while the carriage is moving away from the clamping-plate. These toothed plates 47 are preferab y semicircular, as indicated in Fig. 2, so as to insurethe engagement of the teeth with the fabric as the thickness of the layers increases. a

\ In connection with the carrier-bars we may employ one or more cutters-for slitting the goo s lengthwise as the carria e moves along. These cutters, as clearly in icated in Fig. 10, consist of upwardly-curved blades 48, sharpened on their upper edge and secured as adjusted on the carrier bars by clamping-screws 49, which pass through upper plates 50 and engage with thecarrierars. The cutting-blades are also provided with bottom plates 51 for engaging against the under side of the carrier-bars.

Instead of placingthe goods flatwiseon a table, such as the table 5 we may employ when the goods arein a roll a frame consisting of arms 52, designed to be en ged with the frame 2, and of course at suc time the. supplemental table with its supporting devices willbe removed. These arms 52 are provided with bearings 52 for rollers on which the goods or fabric may be wound, and the fabric will pass over guide-rollers 53, supported by cross-bars on the frame or arms 52.

Extended forward from' each clampingplate 38 39 are fingers 54, having outwardly extended portions 55, designed to engage upon the inclines 36.

In the operation, assuming the carriage to be moving from the righthand end of the cutting-table toward the left-hand end, the

goods orfabric will be clamped by the late 38, and as the layer engages underneat the carrier-bar 26 it will be evenly spread upon the table, and the blade 48, mounted on said bar 26, will sever the fabric longitudinally. When the machine reaches the left-hand end of the cutting-table, the arm 35, depending from the rocking bar 25, will engage upon the incline 46, swinging the carrier-bar 27 upward and enga ing its ratchet-wheel ,31 with the finger 32, t us imparting a rotary movement to the ratchet-wheel and drawing the bar slightly u ward. As the carriage continues the inclined plates 36 on the bar 26 will pass into engagement or against the under sides of the fin er portions 55, swinging the plate 39 u war ermitting the fabric to be carried un erneat the plate by means of the said bar 26. When the finger portions 55 pass over the higher ends of the plates 36, the

plate 39 will swing downward to engage the clutchingldevices 47 with the goods preparatory to t e return movement of the carriage. Upon the return movement the fabric of course will be engaged by the carrier-bar 27 and the parts will be reversed, as above mentioned, at the right-hand end of the table.

As a means for indicating the number of yards or the number of layers of fabric placed upon the cutting-table, we may mount upon the carriage a recordin device 56 of any suitable construction and om the working parts of which arms 57 58 extend outward in opposite directions, these arms being designed for engagement with pins 59 60 on the rocking bars 24 25. These pins not only serve to 0perate the rocking device, but by engaging with the side members of the frame 2 limit the rockin motion of the rocking bars. In other wor s, they would serve to hold said rock-bars in such position as to support thebars 26 27 in contact with the fabric.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1'. In a fabric-foldin machine, a table, a
